Image Sharpen



  • Class name: ImageSharpen
  • Category: image/postprocessing
  • Output node: False

The ImageSharpen node enhances the clarity of an image by accentuating its edges and details. It applies a sharpening filter to the image, which can be adjusted in intensity and radius, thereby making the image appear more defined and crisp.

Input types

FieldComfy dtypeDescription
imageIMAGEThe input image to be sharpened. This parameter is crucial as it determines the base image on which the sharpening effect will be applied.
sharpen_radiusINTDefines the radius of the sharpening effect. A larger radius means that more pixels around the edge will be affected, leading to a more pronounced sharpening effect.
sigmaFLOATControls the spread of the sharpening effect. A higher sigma value results in a smoother transition at the edges, while a lower sigma makes the sharpening more localized.
alphaFLOATAdjusts the intensity of the sharpening effect. Higher alpha values result in a stronger sharpening effect.

Output types

FieldComfy dtypeDescription
imageIMAGEThe sharpened image, with enhanced edges and details, ready for further processing or display.
